You've constructed a proxy for an object on the bus name

and bound to the Notify signal. Then:

a service connects to the bus, receives a unique name like :1.23, and
emits the com.test.Notification.Notify signal from its
/com/test/Notification object. But you bound to signal emissions by
com.test.Notification, not :1.23.
